Follow these steps to connect to 10BASE-T or 100BASE-TX devices:
Step 1
When connecting to workstations, servers, routers, and Cisco IP Phones, connect
a straight-through cable to an RJ-45 connector on the front panel. (See
.) When connecting to switches or repeaters, use a crossover cable.
(See the
“Cable and Adapter Specifications” section on page B-5
for cable-pinout
descriptions.)
Caution
PoE faults are caused when noncompliant cabling or powered devices are
connected to a PoE port. Only standard-compliant cabling can be used to connect
Cisco pre-standard IP Phones or wireless access points or IEEE
802.3AF-compliant devices to PoE ports. A cable or device that causes a PoE
fault must be removed from the network.
Note
You can use the
mdix auto
interface configuration command in the CLI to enable
the automatic medium-dependent interface crossover (Auto-MDIX) feature.
When the Auto-MDIX feature is enabled, the switch detects the required cable
type for copper Ethernet connections and configures the interfaces accordingly.
Therefore, you can use either a crossover or a straight-through cable for
connections to a copper 10/100 or 1000BASE-T SFP module port on the switch,
regardless of the type of device on the other end of the connection.
The Auto-MDIX feature is disabled by default. For configuration information for
this feature, refer to the switch software configuration guide or the switch
command reference
.
Note
The Catalyst 3560 switch can connect to a Cisco IP Phone through a
straight-through, twisted four-pair Category 5 cable. The rear panel of the
Cisco IP Phone might have more than one RJ-45 connector. Use the
LAN-to-phone connector to connect the IP phone to the switch. Refer to the Cisco
IP Phone documentation for more information about connecting devices to it.
